The Americans’ Keri Russell and Matthew Rhys Are a Couple — Report

Life may be imitating art for Keri Russell, 38, and Matthew Rhys, 39! The two actors play a couple on The Americans —and they're now a couple in real life, too, according to People.

The magazine cites sources who say that that the two FX stars looked very lovey-dovey at a March 27 performance of The Library at The Public Theater in New York City, with Keri "stroking [Matthew's] hair."

But the Welshman played coy when People asked him about his rumored on-set romance last month. "That's the best [rumor] I love," he said, adding that he advises his mother to ignore her Google alerts.

People also notes that the two co-stars were spotted looking "very much like a couple" earlier this year as they checked out furniture in Brooklyn Heights.

In December, Keri — probably best known as the star of The WB's Felicity — announced her separation from Shane Deary, then her husband of six years.

Meanwhile, Matthew Rhys — hitherto known for his role on ABC's Brothers and Sisters — once dated Sienna Miller.

Then again, perhaps Matthew and Keri are actually spies faking a relationship, like their on-screen counterparts!
